Introduction

Characteristics

The SP Series of pressure transmitters are designed to measure the level or pressure of
various industrial processes.

Models can be mounted with various threaded or flanged process connections. All
models are available with 4..20mA (2 wire) output (or voltage outputs). The SP/FA line
coms with an integrated Zero and Span adjustment. All units offer excellent stability,
repeatibility, accuracy and temperature compensation. HART communications protocol
is also available for many models.

Each model in this series is offered in pressure ranges that are suitable for various types
of application requirements such as for; liquids, gases, areas with limited space, food
industry, chemical industry or areas that feature aggressive mediums or waste fluids with
varying degrees of suspended solids.

Technology

The SP series utilize the principle of the alteration of resistance or capacitance. The SP
Series is available with sensing elements of either 316 Stainless Steel, ceramic
piezoresistive diaphragms or thick filmed ceramic diaphragms (for more aggressive
mediums or applications).

The external pressure of the medium induces a dislocation of electrical load that
accumulates on the opposite surface of the diaphragm, resulting in an output signal that is
proportional to the pre-calibrated pressure range of the sensor. The electronics converts
this information into either a 4...20mA(2 wire) output signal (standard) or a 1 to 5V (3 wire
optional per custom order), which is directly proportional to the applied pressure of the
process.

Small, robust and easy to install

Reliable measurement of level and pressure.

1) Use PTFE tape or o'rings to seal the system.

2) Before installing, make sure the cable connections are
correct and that the line voltage is compatible with the
specifications of the equipment. Use reliable cables and
make sure that they are grounded. Shielded cables
prevent interference and changes in the eletronic signal,
protecting against false measurement output. Avoid
radio frequency interference as it may also cause false
signals and even create a possible malfunction of the
tr a n smitte r. Wh e n possibl e , ke ep h and h eld
communication equipment away from the SP transmitter.

3) Care should be taken to prevent deformities in the
membrane. You should also be careful not to touch or let
any other object touch the membrane of the sensor
during installation (this does not apply to the units with
ceramic sensing elements) . Any deformity to the surface
of the 316SS silicone filled membrane will damage the
sensor and impair its operation.

Transmitters with cable gland:

Tighten the cable gland as much as possible so that the
cable is securely in place and cannot be pulled through
the cable gland. This will help insure that no moisture is
able to infiltrate into the housing. Don´t forget to attach
the housing cover and tighten all three screws into
position so that there is no infiltration.

4) Protect the transmitter against rain and do not expose it
to excessive heat. Respect the working temperature and
the class protection specified for use.

5) Before installation, for security reasons, make sure the
tank or pipe is empty and without pressure.

6) For transmitters with sealing:
Under no circunstances should you remove the
transmitter seal. Avoid flexing the membrane with your
hands and keep it protected until the installation.

Mounting Notes

11

The transmitters can be installed in various
positions, but the following needs to be taken into
account: For level measurement the installation
should be at the base of the tank or at the point of
minimum level measurement (fig.1). This means
that the reference point for the base measurement
will become the point at which the sensor is
installed which will not necessarily be at the
bottom of the tank.

It is advisable to install a blocking valve between
the transmitter and the connection to perform
maintenance without having to stop the process.

Avoid installing in the tank outlet or near shaker
where there is pressure pulses thus preventing
rapid changes in the signal. For this case it is
necessary the use of still-pipe (Stilling tube) to
absorb the liquid surfaces (Fig. 2).

Principle of Operations

The weight of the column of liquid
generates hydrostatic pressure on the
diaphragm of the sensor. When the
density of the product is constant and
the quantity of the liquid is increased
or decrea se s, th ere will be a
proportional output from the sensor .

Installation

In situations where the tank is suspended, the
transmitter should always be installed in a point
below the connection using the sealing system
with capillary connection. This type of installation
is required when you want to mount the
transmitter in a better position for viewing (Fig. 3) .

Note: Evaluate what type of product is to be
measured. Aggressive products can damage the
membrane of the sensor element or of the o´ring
seal. That is why it is necessary to determine the
compatability of the product before the unit is
purchased and installed. (Fig. 4).

Install the transmitter so that the electrical cable
dips below the transmitter (or makes a "U") so that
water can drain off the cable without the risk of
infiltrating into the transmitter (Fig 5).

Use a cable with vent tube for all Sitron transmitter
models so that the linearity of the output signal and
the operation of the unit is not compromised (this
special cable can also be provided by Sitron) (Fig.

7).

Avoid installing the transmitter underneath a tank
or were splashing or overflow of the product might
damage the unit. If this is unavoidable, install a
barrier to protect the unit from the product
infiltrating from the outside of the transmitter.
This may also be recommended when the
installation is in an open environment. Weather
variations can create internal condensation, so it
is best to avoid exposing the transmitter to direct

Calibration

Z(zero)

Fig.2

Fig.1

SP98FA and SP96FA

Before the calibration of the unit is first tested,
the process should be free of pressure or (if
that is not possible) the unit should first be
tested outside of the vessel.

Make sure the muliti-meter is correctly
connected in series with the source and the
instrument. The scale should be set to mA

First confirm that the current output is at 4mA
(for SPFA units you can adjust the trimpot
"zero".) Turning the trimpot clockwise
increases the current value, and turning it
counterclockwise decreases the value
(Fig.2).

After adjusting (if necessary) the 4mA (zero)
install the unit in the process or fill the vessel
to increase the pressure of the process to the
maximum level desired. If necessary, turn the
trimpot (Span) to adjust the 20mA signal
(Fig. 3).

After calibrating the unit for the first time, it is
recommended that the you re-check the zero
and span ouput with your multimeter. This will
confirm that the unit is properly calibrated or if
further adjustment is necessary.

14

Seal the thread with Teflon tape before
installation.
(Fig. 1).

When tightening the sensor, use only use the
316S.S. hexagon fitting to achieve a seal, do not
twist with the body of the sensor.

The transmitter should not be dropped or suffer
any impact or fall, as this can damage the
electronics or the sensor (Fig.3).

Electrical connection with DIN connector:

Figure 4. Shows the steps for proper assembly of
the connector. When you tighten the threaded
part, stop once you feel that the rubber seal is at its
maximum compression point. Do not over-tighten
the thread. It is very important that the connector is
securely sealed so that the class protection is
maintained and no infiltration occurs.

Do not turn or handle by the housing

(Fig. 2).

Do not insert any object into the entry point of the
transmitter supply. This will immediately damage
the membrane.
